Daniel 6:13

And they came and said to the king, O king, hast thou not made a decree, that whatsoever man shall ask a petition of any god or man for thirty days, but of thee, O king, shall be cast into the den of lions? And the king said, The word is true, and the decree of the Medes and Persians shall not pass.
